This commit first fixes an issue where Alloy did not record when a finalizer thread had already been spawned. This alone removes the finalizer count anomalies and brings performance back up to ~20% slower than our previous finalization model [1]. Second, by introducing a condition variable to sleep the finalizer thread when there is no work to do we now see that our elision benchmark results are statistically indistinguishable to [1]. [1]: Benchmarks run using Alloy from commit #abe23a2c
